CLUTCH DEVICE.

To all 10h am it may mmcm:

Be it known that I, SIM02 -I W. WARDWELL, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and ,useful Improvements in (-lutch Devices, of whieh the following is a Tl'ie'single figure of the drawing is a plan view ilh'istrating my device applied to-.a

driving-shaft and showing the clutch-element and its cooperating driving-member in seetion'on a plane passing through the axis of the shaft. 7

My improved cli'itelrmechn-nism.is especially adapted for use on'brnidiug machines such, for instance, as that shown and described in my United States Patent No.

1908,1304; dated Nov. 14, 1911, and particir lurly in connection. With'the stoppingand braking-devices set forth in my pending application, Serial No. 615,076, filed Mar. 17, 1911. It is'to be understood, however, that my new device might be applied to'othcr muchinesbesides braiders and therefore I do not hereinlimitmyself to the exact use as above mentioned. 7

Referring to the drawings, A designates a driving-shaft arranged to rotate in a hearing B and adapted to (lrive'the machine to which it Connected through suitable transmissionmechanism. not here shown or described. Mounted on the end of: the shaft A is a. clutch-member C formed with a hub 0 bored to receive the shaft and having a. Web ting the annular rim The clutch be: fastened on the shaft in any a n' nnor but :as here own held ling through a transverse hole 1" in t hub o and a corresponding hole a in the split spring'ring 1; enru'rles the I "L- ruin. .1

. hub c in line with the hole 0* and is held in a suitable groo e 0 scored on the periphery of the hub. The ring 0 serves to normally prevent displacement of the pin a, but 01in 1e sprung out of its groove to allow the removal of the pin so that the clutch mebe taken off the shaft when necessa'r'y t I will be noted that the hub o is turned down at c to form a beveled shoulder adjacent one side-of the groove 0 This provides a.

sort of ledge adapted to receive the rixrlgo when the latter is sprung out of the groove 0 and the ring can thus be-held away from the hole a without removing it from "the hub while the pin 0 is being extractedgor put back into place. Therim c of the clutch C is formed with a tapered face 6 adapted to engage with aporrespondingly tapered interior face (I onthedri'ving-memer I). I

:The drivingmcmber D is here shown as taking the Iorm of a belt-pulley. but it obvious that it might be eonstrueted ,ss z-.=

gear, friction-wheel or otli'e'i' similar rotetnble element. The pulley D ismounted rotatably on the shaft A betWeenthecluteh'C and the bearing-B. The bore of its hnb'd' preferably provided withoil-pockets d hafV ing radial holes d leading therefrom to the;

periphery of the hub. Formed as a part of the webD' of the pulley. is an overhanginig, annular flange cl srurouriding the hub The end of the hub d is turneddown zit d and a lianged cap d is driven on. to this re dueed portion with its rim (2 fitted to the:-

flange d. The cap d has a number of redial blades d in its interior and these act to lead the oil into the holesdl- When the parts are assembled oil is placed in the reservoir formed by the flange (if and cap (1 and while the pulley is rotating centrifugal force will tend to throw the oil outward toward the circumferential Wall of the reservoir. The blades d then serve to' break up this ring of oil and act to lead it toward the hub of the pulley so that it drips grad it the outer end of the or pi'ieket d in ing along the is kept thoroughly lu b ri free rotation of the pulley loo shaft A accum""ates, centrifugal action preventing it from escaping at the end of the hub. Longitudinal holes d leading through the hub cl and into the pocket d serve to drain the surplus oil back to the opposite end of the hub d where it is utilized to lubricate a sleeve or bushing 15 arranged adjacent the hub.

The end of the hub cl adjacent the sleeve E is constructed with a peripheral groove (i forming an annular flange (Z Beyond the flange d" the hub d is turned down to form a beveled groove surrounding the extreme end of the hub. Mounted free to turn on the shaft A and abutting the hub (Z' is the sleeve or bushing l) which counterbored at e to receive the outwardly beveled end of the hub d. An interior flange 0 at the end of the countcrhoie e overlaps the groove 11' on the end of the hub (Z and acts to preventthe escape of oil at this point, the natural tendency being for the oil to work outward from the groove (1? to the point of greatest diameter on the hub. The periphery of the sleeve E is formed with an annular flange 6 of approximately the same diameter as the flange d on the pulley-hub d. and is spaced at a slight distance therefrom. Extending longitudinally into the sleeve E are a plurality of holes 0 preferably six in number, which form pockets adapt-ed to receive the coiled springs f. The holes 6 are bored into the sleeve E to within a slight distance of the counterbore e and holes 6 of slightly less diameter lead therefrom into the connterbore so as to form continuous channels extending longitudinally of the sleeve. These channels serve to drain otl the surplus oil leading back through the longitudinal holes d in the pulley-hub d and distribute it to the opposite end of the bearing of the sleeve E. The sp 'ings f bottom in the ends of the larger holes' c with their opposite extremities hearing against a washer F abutting the end of the bearing B. Preferably, the bearing B is formed with a boss 6, which takes the thrust of the washer F, and a hood or cowl b encircles the boss and surrounds the sleeve E throughout a portion of its length. The cowl b is formed with its interior wall tapering radially out Ward, rearwardly from the end of its opening to provide a sort of trough or drip-cup to catch the surplus oil which drains through the holes at The cowl 5 also acts as a spatter guard to prevent the oil from being thrown outward through centrifugal action when the sleeve E is rotating rapidly.

The pulley D is normally maintained in 'engagen'ient with the clutch C through the action of the springs which tend to force the sleeve it against the end of its hub cl.

' To release the pulley from en genent with the clutch I provide means for sliding it on the shaft A in the direction indicated byithe -wardly-extending pin 2:

arrow These means consist essentially of a sliding arm (l formed with lateral pro- ]CtlOnS or lugs g, [1 adapted to engage respectively with the flange (Z on the pulley connection with the explanation of the method of ope "ation of the device.

The arm G is formed with a slotted opening which acts as a guideway or hearing to receive :1 lug extending from the side oi the main bearing B. A stud or screw-H screwed into the lug vis formed with a head it of greater diameter than the width of the slot g and serves to maintain the arm (11 in position on its bearing lug. The opposite end of the arm G is formed with a head 5 overlying one arm is of a lever K, to which it is loosely connected by means of a pin 1: extending through the enlarged hole g". Another arm 1:" of the lever K is adapted to be connected with the manually-operated starting-lever iff the machine through means of a link, cord or other arrangement not here shown or described. "The lever K is pivoted on a stud-or pin k3 extending upwardly from a bracket which projects laterally f-ronrthe hearing B. The lever K has a third arm It which carries an up Pivoted on the pin if above the lever K is a second lever L formed with an arm 1 having a hole I through which. the pin [.1 extends, it beingnoted that the diameter of the hole is greater than that of the pin. to provide a clearance between the two. Pivoted on a pin m at the end of the arm Z isa detent-lever' or latch M formed with a-shoulder m adapted to engage the corresponding shoulder a of a in driven into the bearing'B. The latch M is fastened one end of a coiled spring O-having its opposite end fastened to the end of an arm 1 on the lever L. The latch M also has a lug m adapted to he engaged by the pin on the lever K. The lever L also has a third arm Z to the end of which is attached a spring P, the latter having its opposite end hooked around the head of the stud H in the Waring-lug The spring P tends to swing theiipper T in the direction indicated by the arrow 3 and through the engagement of the side of the hole Z with the pin 12' acts to move the lever K in the same direction.
